摘要

摘要实验证明了一种基于单模-多模单模-多模-单模（SMSMS）光纤结构的温度传感器。SMSMS结构被乙醇-甘油溶液覆盖，改变乙醇与甘油的比例会改变温度敏感性。开发了一种理论计算来表征乙醇甘油含量对传感器性能的影响，。多模干涉（MMI）发生在单模光纤（SMF）和多模光纤（MMF）之间，温度测量是通过监测干涉轮廓在传输光谱中的移动来实现的。结果表明，用乙醇-甘油溶液覆盖SMSMS结构提高了传感器的温度灵敏度。温度灵敏度为0.700 nm/°C从30 °C至80 °C。

Highly sensitive temperature sensor based upon a multimode interference structure filled with an ethanol-glycerol solution

Abstract A temperature sensor based upon a single mode - multimode-single mode – multimode - single mode (SMSMS) fiber structure is experimentally demonstrated. The SMSMS structure is covered by ethanol-glycerol solution, and changing the ratio of ethanol to glycerol changes the temperature sensitivity. A theoretical calculation was developed to characterize the influence of the ethanol-glycerol content upon the sensor performance,. Multimode interference (MMI) occurs between single mode fibers (SMF) and multimode fibers (MMF), and temperature measurements were achieved by monitoring the movement of the interference profile in the transmission spectrum. The results show that covering the SMSMS structure with an ethanol-glycerol solution improves the temperature sensitivity of the sensor. The temperature sensitivity was is 0.700 nm/°C from 30 °C to 80 °C.

期刊介绍： Instrumentation Science & Technology is an internationally acclaimed forum for fast publication of critical, peer reviewed manuscripts dealing with innovative instrument design and applications in chemistry, physics biotechnology and environmental science. Particular attention is given to state-of-the-art developments and their rapid communication to the scientific community. Emphasis is on modern instrumental concepts, though not exclusively, including detectors, sensors, data acquisition and processing, instrument control, chromatography, electrochemistry, spectroscopy of all types, electrophoresis, radiometry, relaxation methods, thermal analysis, physical property measurements, surface physics, membrane technology, microcomputer design, chip-based processes, and more. Readership includes everyone who uses instrumental techniques to conduct their research and development. They are chemists (organic, inorganic, physical, analytical, nuclear, quality control) biochemists, biotechnologists, engineers, and physicists in all of the instrumental disciplines mentioned above, in both the laboratory and chemical production environments. The journal is an important resource of instrument design and applications data.
